Top 3 Best Lawn Mower and Grass Trimmer Combo Picks for 2027

Saturday morning. You pull the cord on the gas mower twenty times, it finally sputters to life, and you make one pass before the string trimmer jams. Then you realize the edger has a separate fuel mix. Before you’ve even finished the front strip, you’ve burned an hour just managing equipment. That routine gets old fast.

A cordless combo kit changes the math. One battery platform runs the mower, the trimmer, and often a blower, so you grab two batteries and go. No gas, no oil, no pull cords, no trips to the station for premix. For yards under a quarter acre, these kits cut the chore time nearly in half.

I have used and tested the top three combos available right now. The list below covers the best overall, the best value for larger lots, and the best budget option for tight spaces. Each one solves a different problem, so read the details before you pull the trigger.

Here is how the top three compare at a glance:

Features	BLACK+DECKER 3-in-1	STEELITE 40V Combo	Greenworks 48V Kit
Best For	Tiny yards & slopes	Flat, mid-sized lawns	Larger yards, hills
Drive Type	Push (convertible)	Push	Self-propelled
Deck Size	12 inches	17 inches	21 inches
Motor Type	Brushed (PowerDrive)	Brushless	Brushless mower
Batteries Included	2 (shared)	2 x 20V 4.0Ah	2 x 24V 5.0Ah
Extras	Edger function	Leaf blower	Leaf blower, side discharge

BLACK+DECKER 3-in-1 Combo

The one you buy when storage space is a premium and your yard is mostly tight corners.

This kit is the ultimate space-saver. The mower deck is actually a wheeled platform that the trimmer snaps into. You get a string trimmer that converts into a small push mower and an edger without buying three separate tools. For a townhouse with a postage-stamp lawn or a yard with awkward slopes that a full-size mower can’t handle, this is a clever solution.

The headline feature is the AFS (Automatic Feed Spool). You never stop to bump the head on the ground to let out more line. It feeds automatically, which keeps the work moving. The PowerDrive transmission also prevents the motor from bogging down when you hit a thick patch of weeds. It is genuinely useful, not just a marketing term.

But there is a trade-off. The 12-inch cutting deck is small. You will not want to mow a half-acre with this thing; it will take forever. It is also a push mower only, so on a steep hill, you are doing the work. The runtime is modest, though the included two batteries help you swap and keep going.

• Converts between mower, trimmer, and edger in seconds
• AFS auto-feed spool prevents line jams
• Two batteries and a charger included
• Adjustable length and cutting height
• PowerDrive tech handles dense grass without stalling

Best for: Homeowners with small, sloped, or oddly shaped lawns who need one tool to do three jobs and store in a closet.

STEELITE 40V 17-Inch Combo

The value pick that bundles a mower, trimmer, and blower for a flat, open lawn.

Steelite targets the buyer who wants a full yard-care kit without paying premium brand prices. This combo includes a 17-inch mower, a weed wacker, and a leaf blower. It is a complete system for a typical suburban lot where you need to mow, trim the edges, and blow off the driveway afterward.

The mower runs on two 20V 4.0Ah batteries in series to deliver 40V of power. The brushless motor spins at 3400 RPM, which gives it enough torque for regular grass. The 2-in-1 system lets you switch between bagging with the 40L collection bag or mulching with the included plug. A single lever adjusts the cutting height across six positions, so you can adapt to seasonal grass growth.

There are a few quirks. The shipping note is important: the mower and blower arrive in one box, and the trimmer comes in a separate package. Do not panic when the first box shows up. Also, the runtime of roughly 25 minutes is on the shorter side, so if you have a large yard, you might need to recharge or buy extra batteries. It weighs 30 pounds, which is light, but that also means the deck is not the most heavy-duty.

• 17-inch steel deck with 2-in-1 bagging and mulching
• Brushless motor delivers 3400 RPM for consistent cutting
• 6-position single-lever height adjustment
• Includes 40L collection bag and mulch plug
• Push-button start, foldable handle for storage

Best for: Budget-conscious buyers with flat, mid-sized yards who need a mower, trimmer, and blower in one purchase.

Greenworks 48V Self-Propelled Kit

The heavy-duty choice for larger lawns and slopes where pushing is not an option.

Greenworks brings the most powerful package here. The 21-inch steel deck mower is self-propelled, which makes a huge difference on hills or if you simply do not want to break a sweat. It runs on two 24V 5.0Ah batteries (48V total), giving it the longest runtime and the most cutting power of the three.

The mower offers a true 3-in-1 system: mulching, rear bagging, and side discharge. That flexibility matters when leaves pile up in the fall or when you want to feed the lawn in the spring. The 7-position height adjustment gives you fine control over cut length. When you are done, the handle folds down and the mower stands vertically to save garage space.

The included trimmer and blower are solid, though they use brushed motors rather than brushless. The blower pushes 320 CFM at 90 MPH, which is enough for clearing grass clippings off a patio. The trimmer has a 12-inch cutting path and an auto-feed head. The whole kit is covered by a 3-year warranty, which is the best in this lineup.

The catch is price. This is the most expensive kit here, and the trimmer line is a standard 0.065-inch, which is fine for grass but not for heavy brush. Also, the dual-port charger is convenient, but charging two 5.0Ah batteries from empty still takes a few hours.

• Self-propelled drive on a 21-inch steel deck
• 3-in-1 system: mulch, bag, or side discharge
• Runs on two 24V 5.0Ah batteries for extended runtime
• Includes trimmer with auto-feed head and 320 CFM blower
• 3-year warranty on tools and batteries

Best for: Homeowners with a third-acre or more, sloped terrain, or anyone who wants self-propelled convenience plus a full accessory kit.

How We Chose These Products

We focused on real-world usability rather than just spec sheets. Each kit was evaluated on how well the components work together, how easy the batteries are to swap, and whether the design solves a specific yard problem. We prioritized kits that offer a complete ecosystem so you are not stuck mixing and matching chargers.

We also considered the long-term cost of battery platforms. Buying into a single brand is an investment, so we looked at warranty coverage, replacement battery availability, and whether the kit covers your whole yard or just the basics. The three picks below represent the best balance of power, price, and practicality for different home situations.

Buying Guide: What Really Matters

Before you buy, think about your yard’s personality, not just its square footage. A flat, open half-acre needs a wide deck and self-propelled drive. A sloped yard demands torque and rear-wheel drive. A small, fenced yard with flower beds needs a maneuverable trimmer more than a massive mower deck. Match the tool to the terrain.

Pay attention to the trimmer head design. Bump-feed heads let you tap the ground to release line, while fixed-line heads require a manual stop and re-thread. The auto-feed systems on the kits above eliminate most of the frustration. Also check the line diameter; 0.065-inch line is standard for grass, but thicker line handles weeds better.

Finally, look at the charger situation. A dual-port charger is a must if you have a larger yard, because you will drain both batteries and need to refill them quickly. Single-port chargers mean more downtime. Also, consider where you will store the batteries. Extreme heat or cold degrades lithium-ion cells, so keep them indoors during winter.

Our Top Recommendation

The Greenworks 48V kit is the best overall for most homeowners. The self-propelled drive, 21-inch deck, and 3-in-1 mulching options make it a genuine gas-mower replacement. It handles hills, thick grass, and fall leaves without bogging down. The 3-year warranty also protects your investment better than the others.

If your yard is smaller or your budget is tighter, the STEELITE 40V combo is a strong runner-up. It gives you a blower, which the Greenworks kit also includes, but at a lower entry price. For tiny yards and apartments with outdoor space, the BLACK+DECKER 3-in-1 is the smart pick because it replaces three separate tools.

Frequently Asked Questions

How long do the batteries actually last in real use?

Runtime depends heavily on grass conditions. On a dry, thin lawn, you will get close to the advertised maximum. In thick, damp grass, expect roughly half that. The Greenworks kit with two 5.0Ah batteries will outlast the STEELITE’s two 4.0Ah packs. Plan for about 20–30 minutes of continuous mowing per charge cycle on average.

Can I use the trimmer battery in the mower?

In these kits, yes. The batteries are shared across all tools. That is the main advantage of a combo kit. If one battery dies in the mower, you can swap it with the one from the trimmer. Just make sure you buy a kit where the voltage and amp-hours are identical across batteries to avoid performance issues.

Is a brushless motor worth the extra money?

Brushless motors are more efficient, quieter, and last longer than brushed motors. They also deliver more torque for the same battery draw. The STEELITE and Greenworks mowers use brushless motors. The trimmers and blowers in these kits are mostly brushed, which is fine because they run for shorter periods. If you are cutting thick grass, prioritize a brushless mower motor.

What is the best way to store the batteries over winter?

Remove the batteries from the tools and store them at room temperature, ideally around 60–70°F. Do not leave them on the charger all winter. Charge them to about 50–60% capacity before storage. Check them every couple of months and top them up if they drop below 30%. This preserves the cells and prevents the pack from dying permanently.
